Today, scientists from the University of Illinois at Urbana-Champaign have discovered a new type of exciton in a class of materials known as strongly correlated insulators. This exciton, known as the Hubbard exciton, has the potential to revolutionize the way we think about electrical current and heat transfer in these materials. Unlike conventional excitons, which can only transfer energy along a single path, the Hubbard exciton can transfer energy in multiple directions simultaneously. This could lead to new ways of controlling electrical current and heat transfer in these materials. These findings are an exciting step forward in our understanding of these materials and the potential of using them for energy applications.
